Newbie questions here: I want to describe our current setup that is costing our business a fortune each month and then work on educating myself on how to replicate most of what we have now, but in a SIP system with 3CX. I'm looking to save about 75% of our monthly cost by using 3CX, and I can't wait. I've posted a couple other threads similar to this, but on disparate subjects, and I'm still confused about the "how" to get this all done. Current: a) 4 copper lines from the street, directly corresponding with 4 line buttons (labeled Line 1, Line 2, etc.) on our phones. All incoming calls ring on all phones; any phone can answer any call, and each phone can access all 4 lines for outbound calling. Are these four lines considered "accounts" in the SIP world? So if I want 6 incoming calls to act as they do now, but in a 3CX system, I need to setup 6 accounts on each phone? I have a ring group for all phones setup in 3CX, but I can't figure out how to have all calls ring at all phones (with the exception that if a phone is already in use, it shouldn't ring, but rather blink). Also related to item a, how does 3CX provision phones with 6 accounts? Of course, maybe I'm all wrong in thinking I need to use 6 accounts. b) after the secretary answers the call, she pushes Hold and then pages the employee who the call is for. She says "Tom line 1 please" because she can see that the incoming call was on Line 1. Tom then walks to the nearest phone and pushes the Line1 button. This works great because our workers are mobile and go all over our warehouse. Is this feature what is called Shared Park? And if so, do I dedicate 6 buttons to SP1, SP2, SP3, etc. so that the secretary can use the first available park slot for the call and can announce the park slot on the page, plus so Tom can easily pick up on whichever park slot he needs to? c) our phones now have a button for each extension that shows whether or not the extension is in a conversation, and these buttons also work for intercom. So on the button labeled Tom, I can see if Tom's phone is in use, plus I can push the button to intercom his phone. Is this first feature BLF? If so, is there a way in 3CX to combine BLF and intercom on one programmable button? d) our overhead paging system is powered by Bogen controller and amp. Any suggestions on how to interface this with 3CX? What do the rest of you who have overhead paging with 3CX use for paging controllers? Cyberdata controllers? Thanks for any reply on this!
